I have shown my invention embodied-.in the present instance vin .aIronteed Remington 'type- Writing machine v.in which .the devices of .mypresent 'invention .may readily 'be incorporated without materiallymodifying the existing structural r features `of saidmachine, .as willhereinafter appear.

The .carriage .of the .machine comprises a truck (Gl. 19T-127) .havingend bars 1,.a front cross bar 2 and a rear cross '.bar .3. The .front.and rear cross bars Aare .oppositely .grooved to .form race-ways whichreceive .crossed anti-friction lbearing rollers 4 by which .the.carriage is supported 'totravel over the' .top lplate of the machine.from .side to side thereof. The .bearing rollers 4 .also are received,in oppositelygrooved race-ways in a front xed .guide rail .5 .and arear .xed guide rail 6. The truck supports a platen frame comprisingsuit- 55, vvably connected end plates .7 united to the truck .tor case.shiftingmovement on the latter by parallel .links 8 and 9.. In thepresent instance the lower .case shift screw stops 10 are adjusted .upto hold .the platen frame and cylindrical 70 platen 11 carried therebyin the upper case position, upper -case type only being employed in thepresent instance.

,I prefer .to employ the usual front deilector plate ,12 rpivoted .at1.3 to .the end plates 7 of the 75 platen frame and shiftable from thefull line to the .dotted line position represented in Fig. 3. This .is.order to .facilitate the introduction of the Ylower ends of the Worksheets 14, which constitute a pack `ot sheets vto be written on, into aSQ space `vor channel 1'5 between a deflector plate .1.6 .and .the.lower surface of the platen. In the present .instance the deflectorplate V16 constitutes .a part `of .a paper table 17 provided with.apertured earsl on the rear side .thereof to receive the yusual crossor .tie rod 19 by which the end plates '.7 .of the platen are connected.Curved spacing members '20 vare secured to the deflector 16 .near .theends thereof and are adapted to .bear .against the bottom surface of the.platen in order to .maintain the deilector 16 spaced .apart `from theplaten and thus provide the chan- .nel 15 .referred to. Adjustable cams'21 are secured .byscrews 22 to the usual cross 'bar v23 .that unitesthe side plates '7 of the platen frame. A 95 .loosening .of .the screws22 affords .a rotative adjustment of the cams ,on the screws, whereas atightening lolf vthe .screws 22 secure the cams in their .adjustedpositions. These cams bear against the bottom of the deflector 16 andmain- '100 tain it positioned with vreference to the platen.

In the present instance I provide Athe usual means for controlling themotion of the front deector 12 .from the full to the dotted lineposition shown in LFig. 3 and vice versa. Such means 105 comprise acrankvarm24 .(see Fig. 2) operatively connected to .thedeflector l2 .andprovided with .a laterally projecting pin '2.5 .received in a cam .slot.26 of .an `arm 27, pivo'ted .at `28 to va side plate T7.. Two of these.arms 27 ,are usually provided, 110

temporarily in the dotted line position shown in Fig. 3.

A link 30 is provided at its rear end With-a laterally projecting pin 31adapted-to slide .in .a slot 32 in a bracket plate 33. The rear endV ofthe link 30 is thus supported for movement fore and aft of the machineand has a path of movement tc cooperate with the left-hand arm 27'andshift the latter forward, thereby moving the deiiector 12 from the fullto the dotted line position in Fig. 3. The forward end of the link 30 ispivoted at 34 to a crank arm 35 which ter.- minates in a finger piece36and is secured to a rock shaft 37.Y This rock shaft extends from sideto side of the machine and passes freely through openings in two bracketarms 38 and 39.

The bracket arm 38 is detachably connected to the carriage beingprovided with a foot piece 40 apertured to receive the upper case shiftscrew stop 41 and to be clamped in position on the carriage by a nut 42received on the upper end of said screw stop. The stem of a headed screw43 passes through an opening in a second foot piece 43a on the bracketarm. 38 and engages in a tapped opening in the left-hand end bar 1 ofthe carriage. This bracket arm is apertured to receive and permit therock shaft 37 to pass freely therethrough.

The bracket arm 39 is detachably securedto the carriage by screws 44 andis bifurcated at its rear end to straddle the tie rod 19. The rock shaft37 ordinarily constitutesA part of a controlling means for a series ofpaper feed rolls for shifting them into and out of effective position.However, inasmuch as there is'no necessity for using these feed rolls inthe present construction, they and their controlling companion devicesare stripped from the shaft 37. The construction, however, is such thatwhen the finger piece 36 is moved forward, it and the front deflector 12controlled thereby, will be maintained in the effective dotted lineposition shownin Fig. 3, so as to leave both hands of the operator freeto insert the pack of work sheets in the machine as will presentlyappear.

The construction thus far described is substantially like that employedin the Remington front feed machine except as hereinbefore pointed outand except that a single deflector plate 16 is employed instead of adouble deiiector plate, and there is a slight change in the manner ofsupporting the combined paper table and deflector plate in the presentinstance. Moreover, the detachable bracket arms 38 and 39 have beenadded to the machine by me to provide an effective support for certainof the devices of my present invention.

A supporting bar 46 is secured at its ends by screws 47 and 48 to thebracket arms 38 and 39 respectively, and is maintained in an inclinedposition as indicated in Fig. 3. Spacing sleeves 49 are interposedbetween the upper face of the supporting bar 46 and a frontpaper table50', whereas screws 51 pass through said sleeves and engage the papertable 50 to iixedly support it in place, as represented in Fig. 3. Fromthis figure it will be seen that the paper table 50 is arrangedVprovide'the following devices on each slide.

substantially tangential of the platen at the front thereof Where worksheets supported on said paper table may pass around the platen into thechannel 15 and be held in a bent condition snugly against the face ofthe platen at the printing line, as indicated in Fig. 5. In order tosupport thepack of Aworksheets in this position, and in a fixed relationto the printing line, indicated by the arrow a in said figure, I providethe devices which will now be described.

I.The paper table 50 is provided with upright slots 52 therein toreceive supporting and guiding means provided on two slides 53. This isin order to guidesaid slides in their adjustment towards and from the.platen. These slides are alike in construction and the description ofone will sufiice for both. Each plate-like slide 53 is provided with adepending under-cut stud 54 (see Fig. 6) adapted to extend through thecompanion slot 52 in the paper table to guide the slide along said vslotandf provide against an accidental detachment of the Yslidev from thepaper table 50. A headed screw 55 carries an off-set pin 56. The stem ofthis screw an-d the off-set pin 56 pass through the associated slot 52in the paper table and prevent a turning movement of vthe screw.

The stem of this screw` and also the pin 56 likewise extendthroughopenings in the companion slide 53. of the'screw 55 and at itslower end bears against the associated slide or plate 53 thus binding itin its adjusted position when the thumb nut 57 is tightened. lA backingup of the thumb nut releases the slide and permits it to be adjusted upand down on the paper table.

Each slide 53 is provided with an impaling pin 58 projecting forwardfrom the face thereofl and adapted to be received in openings in theupper edge portions of the work sheets 14, and thus support them attheir'upper ends on the paper table 50. The work sheets are thussupported in a pack of twelve or fifteen sheets in superposed relationand `in` exact registration, it being understood that both of the slides53 are adjusted up or down to the same height, as indicated in Fig. 1 ofthe drawings. The work sheets v14 are preferably ruled horizontally andprovided with vertical columns for filling in various data undercaptions at the heads'of said columns such as Piece work, Day'work, Cashallowance, Bonus, Over time allowance, Total, etc., etc. The intent inthe present instance is to provide a monthly or weekly record on eachhorizontal line of each 'work sheet'. At the end of each month or week,the entry on the various 'work sheets will be made 'on a given line, thenext entry being at the end of the next month or week and so on.

In order to facilitate the proper adjustment of the slides 53Vtowards orfrom the platen so as to bring the proper line on each work sheet toposi- 1 tion at the printing line, I have provided a scale or'series ofindices for each slide, so that the slides maybe successively registeredwith suc-v cessive indices on the scale and thereby quickly position theslides -to the proper positions to receive the work sheets for any givenmonth or week. The markingsor 4indices on each scale are indicated at b,and an indicated mark or pointer c on each slide is 'adapted to'register with the marks on the scale and thus indicate the proper ipositioning of the slides with reference to the l scales.

In order to prevent an accidental detachment of the work sheets from theimpaling pins 58 I A thumb nut 57 engages the threaded end.

"Ti n.

holding device designated as a Whole by the reference numeral 59 is inthe nature of a sheet metal slide movable up and down on its companionadjustable member or slide 53 into and out of effective position, theformer position being shown in full lines in Fig. 6, and the latterposition in dotted lines in said figure. It will be seen from this gurethat each slide 59 has an inclined contact face 60 adapted to overlapand coact with the upper edge of the outermost sheet 14 on the pack ofwork sheets and to maintain it and the sheets beneath it from accidentaldetachment from the impaling pins. When, however, the slides 59 aremoved upward to the dotted line position represented in Fig. 6, the worksheets are free to be withdrawn from or placed on the irnpaling pins. Iprefer to spring press these members 59 to effective position andtherefore connect each of said members with a contractile spring 61anchored at one end on a pin 62. on the companion slide 53 and connectedat its other end to an ear 63 on the companion holding member 59. Eachholding member is held on its oompanion slide 53 and is guided andlimited in its up and down movements thereon, by two headed pins 64secured to the slide 53 and the stems of which are received in a slot 65in the companion locking member.

When impaling the work sheets on the pins 58, it may be found desirableto retain the locking members 59 in ineffective position, and I havetherefore provided latching means for this purpose. Such latching meanscomprises a latch 66 pivoted at 6'7 on the companion slide 53 and havingan engaging nose that is adapted to be received in a locking notch 68 inthe companion locking member 59. When seated in the locking notch, thelatch will retain the locking member in its uppermost, ineffective,position against the force of the companion spring 61.

In' the use of the construction of my invention a series of superposedwork sheets 14 are impaled on the pins 58 and the slides 53 are adjustedto bring the requisite line for entry on said sheets to the printingline. Assume, for example, the uppermost printed line beneath theprinted headings on each work sheet is to be brought to the printingline, the slides 53 will be adjusted down to a corresponding positionfor this purpose and secured in such position by tightening the thumbnuts 57. The writing of the single line entry will then be effected onthe outermost work sheet of the pack. The entered sheet will then beremoved and an entry made on the work sheet beneath it, and so on untilthe pack of sheets is exhausted, when a new supply may be impaled on thepins 58. The next weeks or months entry will require an adjustment ofthe slides to the next higher index mark on each scale and a pack ofwork sheets having been introduced in the machine and impaled on pins58, the entries on the sheets may proceed as before.

It will be seen that the paper dei-lector 16 below the platen willreceive the lower end portions of the sheets of the pack and guide andmaintain them in proper position whatever may be the positions ofadjustment of the slides 53. Said deector will also maintain the sheetsat the lower end portions thereof in proper relation to the platen sothat the deflector 16 in conjunction with the impaling pins 58 and theholding means for the top of the work sheets will maintain said worksheets bent to conform to the surface of the platen and maintain thesheets snugly against the front face of the platen at and adjacent tothe printing line for the proper entry of writing lines thereon.

In order-to properly direct the lower end portions of the Work sheets tothe deflector 16 and prevent a lateral displacement of the pack withreference to the paper table 50, I have provided side edge'guides orgages 69 (see Figs. 1 and 3) whichV are secured to and project upwardlyfrom the supporting bar 46 and coact with the pack of work sheets ateach side of the paper table 50. These side edge guides or gages 69 areof sufficient depth to coact with the side edges of the entire pack ofwork sheets and accurately maintain the sheets against lateraldisplacement.

Various changes may be made in the construction without departing frommy invention as it sheet or card impaling pins carried on said papertable, and of a character to receive a plurality of work sheets orcards, means for affording an adjustment of said impaling pins towardsand from the platen to any one of a plurality of line space positionscorresponding to the months or weeks of a year and on which pins may beimpaled the upper ends of a plurality of work sheets or cards to be heldin place thereby while the work sheets or cards are being written, and apaper apron arranged beneath the platen and maintained spaced aparttherefrom to receive the lower end portions of said plurality of worksheets or cards introduced downwardly and rearwardly from the front ofthe platen, the relation of the said paper table and apron being suchthat a thick pack of Work sheets or carols may be maintained in a bentcondition in conformity with the surface of the platen at and near theprinting line to receive the impress of the types.
